Hello,
I have rewrote completely my wmii patch, and I think that it is more in
the dwm way now. The row layouts are missing but I will add them if the
col layouts fit the dwm way. I have not fully tested it yet so there
might be some bugs. I am currently using it to find them and fix them.
Well, Anselm, thank you for explaining me last time and tell me if the
new patch is better. It has the same features except for the pertag one.
And I think it better interacts with dwm code even if for the
dwmiiresize() function I had to patch the resizemouse() and attach()
functions. If you remove the dwmiicostum2() layout there is only two
lines of patch in the attach() function which is not heavy patching.
Well tell me what you think about it.
Kind regards.
QUINTIN Guillaume

*
* dynamic window manager is designed like any other X client as well. It is
* driven through handling X events. In contrast to other X clients, a window
* manager selects for SubstructureRedirectMask on the root window, to receive
* events about window (dis-)appearance. Only one X connection at a time is
* allowed to select for this event mask.
*
* Calls to fetch an X event from the event queue are blocking. Due reading
* status text from standard input, a select()-driven main loop has been
* implemented which selects for reads on the X connection and STDIN_FILENO to
* handle all data smoothly. The event handlers of dwm are organized in an
* array which is accessed whenever a new event has been fetched. This allows
* event dispatching in O(1) time.
*
* Each child of the root window is called a client, except windows which have
* set the override_redirect flag. Clients are organized in a global
* doubly-linked client list, the focus history is remembered through a global
* stack list. Each client contains a bit array to indicate the tags of a
* client.
*
* Keys and tagging rules are organized as arrays and defined in config.h.
*
* To understand everything else, start reading main().
